TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

CL-ANA is a data analysis library in Common Lisp providing tabular and binned data analysis along with nonlinear least squares fitting and visualization.

This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

This is a Commin Lisp library for operating on permutations and permutation groups.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

Cluster is an assembler (initially for x86 and x86-64) with a difference. To avoid the issue of defining a syntax, the input to Cluster is a list of standard objects (i.e., instances of the class STANDARD-OBJECT), as opposed to a character file or S-expressions.

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

This is a system implementing an advanced dialogue system that is capable of complex dialogue flow including choice trees and conditional branching. Speechless was first developed for the "Kandria" (https://kandria.com) game, and has since been separated and made public in the hopes that it may find use elsewhere or inspire other developers to build similar systems.

Speechless is based on the "Markless" (https://shirakumo.github.io/markless) document standard for its syntax and makes use of Markless' ability to be extended to add additional constructs useful for dialogue systems.

Speechless can compile dialogue from its base textual form into an efficient instruction set, which is then executed when the game is run. Execution of the dialogue is completely engine-agnostic, and only requires some simple integration with a client protocol to run.

Thanks to Markless' extensibility, Speechless can also be further extended to include additional syntax and constructs that may be useful for your particular game.

trivial-download allows you to download files from the Internet from Common Lisp. It provides a progress bar.

This library is a portable compatibility layer around package local nicknames (PLN). This was done so there is a portability library for the PLN API not included in DEFPACKAGE.

QURI (pronounced "Q-ree") is yet another URI library for Common Lisp. It is intended to be a replacement of PURI.

This is a Gettext-style internationalisation framework for Common Lisp.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.
